I've seen a number of shooters on the 1200 yard line at ETTS with rifles chambered in the 6mm - 6.8mm class of cartridges, including the Ruger Precision in 6.5 Creedmoor. My son's former boss is a very long range shooter, and his favorite rifle is a .260 Remington-chambered AR10 platform.....with many many ducats sunk into building it. Why that platform, and not a bolt gun, I don't know.....but he does know a lot about long range shooting. He even wildcatted a new cartridge of his own design not too long ago, which is currently under consideration by SAAMi, called "568 DMR" for long range shooting and still clocks supersonic at 1,300 yards. I believe it is a heavy-for-caliber 5.56mm bullet like a 90 or 100 grainer, in a 6.8 SPC case, or something like that. He currently owns the only set of dies and chamber reamer for it, but there's gold in them thar hills if SAAMI standardizes it.Legionnaire wrote:I went through the same due diligence a while ago. My .308 was plenty accurate out to 800 yards, but I still wanted a 6.5. After my research, I decided to go with a .260 Remington instead of the 6.5 Creedmoor. The ballistics are virtually identical, and the .260 uses the same parent case as the .308. Since I have lots (and I mean lots) of .308 brass (as well as a good supply of .243), I decided to go with a cartridge for which it would be easy to form brass from stock on hand. You sound like a reloader; something to consider.
Anyway, the guys with their Ruger Precision rifles in 6.5 Creedmoor seem to enjoy them a lot, and they are getting pretty decent long range accuracy out of them. My problem is that I am already fairly invested in .308, both in rifles and in reloading components, as well as rifles and reloading components for .223/5.56......and I've also taken on reloading for .300 Blackout. I am not anxious to take on another rifle caliber at this point. (I have a box of unsorted spent.308 brass that weighs an easy 50 lbs or more, and another that weighs just a little more, full of unsorted spent .223/556 brass!) I've gotten my .308 Remington 700 out to 800 yards so far, and with practice hope to get it out to 1,000 - but that's just an arbitrary number that is about as far as I think I would be capable of hitting anything reliably. 800 yards out may not seem like much to people who haven't shot at that distance, but it is a darn long ways. I don't anticipate ever needing to hit something at that range besides a piece of steel plate or a paper target. So for me, the 1,000 yard line is just a benchmark I'd like to achieve for its own sake. My instructor told me he was hitting targets of opportunity at 1,300 yards in Afghanistan with a .308 bolt gun (he is a retired MARSOC scout sniper), so I have no doubt that the rifle will reach that far. I just have a lot of doubt that this shooter can do it. So 1,000 is the limit I set for myself. If I can do it with this rifle, I'll be happy.
I haven't considered buying one of the new class of precision rifles from any manufacturer, but I have considered investing in a chassis system for the Remington I have - which is currently stocked with a tan HS Precision Varmint profile stock similar to the old M40 profile. But that stock does not have any adjustability built into it, and whereas it is fine for shooting from the bench, I'm finding the comb too low and the length of pull too long for shooting from the prone. I've adjusted the comb upwards with a neoprene sleeve with inserts under it, but the LOP is still too long for comfort. So I'm looking at chassis systems that are within my price range that will give me that adjustability in both planes without breaking the bank.
